Which statement below explains why water is insoluble in the middle of the semipermeable membrane.
GenaCL600 [577]

Answer:

The membrane is made from polar phospholipids allowing water to move freely in and out of the cell

Explanation:

The cell membrane is the organelle of the cell that allows for substances to be transported into and out of the cell. It is able to do this due to its semi-permeability. The membrane contains a phospholipid component, which contains a polar region that allows for polar substances such as WATER to enter and leave the cell.

The polarity of the phospholipid component of the cell membrane explains why water is insoluble in the middle of the semipermeable membrane.
